Jan Brueghel just outbattled stablemate Illinois as Aidan O’Brien saddled the first two home in the Betfred St Leger at Doncaster.
Following on from the success of Continuous 12 months ago, the master of Ballydoyle has now claimed the world’s oldest Classic eight times.
He was holding all the aces entering the home straight, with Grosvenor Square leading from Illinois and Jan Brueghel.
Grosvenor Square was passed at the two-furlong pole, from where 11-4 joint-favourites Illinois and Jan Brueghel took control.
And it was Jan Brueghel, partnered by former Ballydoyle apprentice Sean Levey, who ultimately stayed on the strongest to get home by a neck and stretch his unbeaten record to four.
